Baby socks purchased from brands like Mezzo Piano, Petit main, and Birthday. All but the Birthday socks have non-slip grips. The Birthday socks are 7-9cm. The exact sizes of the others are unknown, but they were used around the same time, so they are likely similar in size. (Sizes are registered as a placeholder) *Although there was almost no opportunity to use them and there are no noticeable stains or marks, these are used items worn by a child, so they are not new. Please refrain from purchasing if you are looking for new items. Individual sales are not possible. Price reductions are not possible. Thank you for viewing.
